Floral trait similarity at the community‐level increases reproductive success suggesting facilitation through pollinator sharing

Oikos, EarlyView.
The ability of plants to attract pollinators is context‐dependent, influenced by floral traits, abundance, and resources from the plant community. Indirect interactions through shared pollinators, from competition to facilitation, may lead to varied reproductive outputs in plants, and the mechanisms behind these interactions remain to be fully ...

Assessing the evolutionary distinctiveness of a highly threatened plant group: The urgency to preserve a unique lineage of evolution in Brazil

PLANTS, PEOPLE, PLANET, EarlyView.
Brazil's diverse flora is under several threats, with many unique lineages facing extinction, particularly in biodiverse regions like the Cerrado and campo rupestre. This study sheds light on the conservation needs of Cambessedesia (Melastomataceae), an endemic genus with 95% of its species endangered, using an approach to rank and prioritise species ...

Fire shifts the soil fertility and the vegetation composition in a natural high-altitude grassland in Brazil

Environmental Challenges, 2022
The Serra da Calçada Mountain (Minas Gerais State, Brazil) hosts a natural grassland with high biodiversity and endemism, locally known as campo rupestre, which grows over hematite and quartzite outcrops, protecting several headwaters.

Ants in Burned and Unburned Areas in Campos Rupestres Ecosystem

Sociobiology, 2016
Ground-dwelling ants have shown consistent resilience to fire in savanna environments. We carried out a study to investigate how ant community structure responds to fire in a harsh and fragile Cerrado ecosystem, the campos rupestres. We studied the change in the ant communities on a local scale subjected to fire in two rocky outcrop habitats at two ...

Estimating costs of ecological restoration across degradation scenarios in South Brazilian grasslands

Restoration Ecology, EarlyView.
Abstract Introduction Grassland ecosystems are among the most threatened worldwide, and the Campos Sulinos—a region of subtropical grasslands in southern Brazil—experiences degradation driven by multiple factors. This study provides initial cost estimates for different restoration approaches, offering guidance for technical and budgetary planning ...

O fogo é sempre um vilão nos campos rupestres?

Biodiversidade Brasileira, 2011
Os campos rupestres ocupam menos de 3% das áreas de Cerrado e Caatinga, mas abrigam uma proporção significativa das espécies vegetais vasculares presentes nestes biomas. Embora várias adaptações ao fogo já tenham sido descritas para savanas do Brasil, ainda há carência de estudos sistemáticos do efeito do fogo nos campos rupestres.

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna

Biological Reviews, Volume 101, Issue 1, Page 74-105, February 2026.
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...
